Towards intelligent PID control

Predictive Pid Control

Model predictive control has proved its effectiveness in many industrial applications. Predictive algorithms are available in various commercial control packages but their implementation costs could be considerable. Control of industrial processes is often realized using small industrial controllers that offer only simple control structures, like PID control loop. The aim of the paper is to der...

Robust Constrained Pid Control

The paper describes some new aspects of the course on Robust Constrained PID Control that is being developed and tought at the Faculty of Electrical Engineering and Information Technology of the STU in Bratislava for more than two decades. New important notions enabling more effective treatment of the carried out analysis and design are introduced and computer tools enabling to achieve homogeno...

PID Control Design

Many industrial applications have digital closed loop control systems and the main algorithm used at these applications is the Proportional Integral Derivative structure (PID). This chapter presents some useful MATLAB commands that might be used as an instrument to analyze the closed loop and also to help the control system design. The first part presents the general standard structure of this ...

Understanding PID Control

A mechanical flow controller manipulates the valve to maintain the downstream flow rate in spite of the leakage. The size of the valve opening at time t is V(t). The flowrate is measured by the vertical position of the float F(t). The gain of the controller is A/B. This arrangement would be entirely impractical for a modern flow control application, but a similar principle was actually used in ...
